Way worse, too much cam for your combo....431 at 6500 (see, the rpm range is going up) and 395 Tq at 5000. Your first choice will give you a much better performer. I had a similar cam to your second choice in a very similar engine, and it was a complete dog! Dont go there, you'll be sorry. Stay with a smaller duration, that's where your torque is built. You wont feel HP, it's torque that you feel, and that accelerates your car. If you want a nasty idle, get the lobe center at 108 instead of 112 or 110. But keep the duration reasonable. I ran a Comp Cams 262 in a 454, it was a solid lifter cam...but the torque was tremendous! Duration on that one was 230/236 I think at .050. So you dont need a lot.
